In addition to his own Music Mondays series, Justin Bieber lends his talents to Tyga on his new single “Wait for a Minute.” The Young Money rapper took to Power 106 this morning to unleash the official song after a previous version leaked in September.

It was originally recorded for Bieber, but will now serve as the first single off Tyga’s upcoming album The Gold Album: 18th Dynasty.

“That’s the new mature Bieber, so I just felt like it was great to do a record with him at this turning point in his career,” T-Raww told Yesi Ortiz. “Musically it just reminds me of when Timberlake got with Pharrell, when he went from *NSYNC to Justin Timberlake.”

The Gold Album: 18th Dynasty is due in the spring. “It’s gonna be a real good album,” he said of the follow-up to April’s Hotel California. “It’s gonna be more kinda how like Careless World, my first album, was… It’s way less commercial. I felt like Hotel California was more commercial and I made more radio-type records. This album is straight rap.”
